1. Feedback control of reproduction in Atlantic salmon, Salmo salar, male parr
Abstract : In fish, as in other vertebrates, the gonads are stimulated by two pituitary gonadotropic hormones, follicle stimulating hormone (FSH) and luteinizing hormone (LH). LH and FSH secretion are regulated by the gonadal steroids acting either directly on the pituitary or indirectly via the hypothalamus. READ MORE

2. How the sensory ecology of the bumblebee affects their functional traits
Abstract : Morphological traits are important for trait-based ecological studies as they allow for the prediction of biodiversity across the biosphere. Currently, the predictive power of trait-based ecology is not often applied to terrestrial arthropods, even though they provide us with important agricultural, ecological, and cultural value.

3. Regulation of insulin producing cells, stress responses and metabolism in Drosophila
Abstract : In Drosophila, neuropeptides have regulatory roles in development, growth, metabolism and reproduction. This study focused on GABA and the neuropeptides Drosophila tachykinin (DTK), short neuropeptide F (sNPF), adipokinetic hormone (AKH), corazonin (CRZ) and Drosophila insulin-like peptides (DILPs) as possible regulators of metabolic stress responses and homeostasis.

4. Chemical circuitry in the visual system of the fruitfly, Drosophila melanogaster
Abstract : Signal processing in the visual system is mediated by classic neurotransmission and neuropeptidergic modulatory pathways. In Dipteran insects, especially in the fruitfly Drosophila melanogaster, the morphology of the visual system is very well described. READ MORE

5. The role of insulin signaling during development, reproductive diapause and aging in Drosophila Melanogaster
Abstract : The insulin/insulin-like growth factor signaling pathway exists from invertebrates to vertebrates and it can regulate various biological processes, including development, metabolism, stress resistance and lifespan. In Drosophila, eight insulin-like peptides (DILP1-8) have been found. READ MORE
